Abstract
To fully understand the potential of condensate throttling in load regulation,simulation tests were carried out on a supercritical 600 MW unit. The effects of condensate flow on unit load,deaerator water level and other parameters were investigated. The simulation results show that the condensate throttling can effectively increase the unit load response speed. However,it will lead to large fluctuation of the deaerator level,which has hidden danger to the unit's safe operation. On this basis,carrying out technical transformation about condensate throttling participating the coordination control can effectively improve the unit's automatic generation control( AGC) load response rate.
